Have a 2007 non-MC 20,000 miles bought new. Noticed an oil leak on garage floor that I investigated today. Coming from 1/2" diameter access or vent area on bottom of crankcase. Looking into hole, see the starting ring (flywheel). MC has an automatic transmission. Appears like a main seal leak.
Anyone with similar experience or have heard of same or recall situation. Thanks.

 

sure sounds like a rear main seal. i have read on thi forum and couple of others who had the same thing.not a ton of others.

 

That's a failed QC. non-MC?

 

Sorry for error in description, 2007 Mini Cooper, non-s.
